Product Description

PCS3P7100A is a versatile spread spectrum modulator

designed specifically for a wide range of clock

frequencies. The device addresses the need of a low

EMI clock generator for use in display systems covering

wide choice of pixel frequencies.

PCS3P7100A

reduces

electromagnetic

interference

(EMI) at the clock source, allowing system wide reduction

of EMI of all clock dependent signals. PCS3P7100A

allows significant system cost savings by reducing the

number of circuit board layers, ferrite beads, shielding

that are traditionally required to pass EMI regulations.

The Supply Voltage of the Device is 3.3V/2.5V. It has two

Spread Selection Pins, SS1% and SS2%. Refer to the

Spread Deviation Selection Table for details.The Device

is available in 6 Pin TSOT-26 Package, in Commercial

and Industrial Temperature grade.

Application

PCS3P7100A is targeted for use in Display Systems
